Rapid Tooling Manufacturing Technology Research Based On Reverse Engineering And Rapid Prototyping

With the increasingly growth of market competition, it is demanded that enterprises must respond quickly to the market and consumers'changing requirements.Meanwhile, industrial productions have been approaching to diversity, mini batches, high quality and low cost styles. In order to take the priority in the competition, enterprises must be able to respond quickly to the market requirements and realize the production style of diversity, mini batches and smartness.Rapid tooling manufacturing technology based on reverse engineering and rapid prototyping are one of the rapid developing technologies in the field of rapid prototyping..It can respond rapidly to reverse engineering of models, and so it can promote the efficiency and accuracy of design as well as shorten the period of designing.The article refers to the domestic situation of developing and application in reverse engineering using a three-dimensional scanner as the research tool in the digital equipment of reverse engineering.A deep research has been done into the rapid curved face modeling on how to reduce the errors in reverse engineering on purpose of initializing the original geometry parameters.According to the resources of home and aboard, the article has introduced the features and some typical technics on rapid prototyping technology.It has also mentioned the main problems that exist as well.The features and problems have also been illustrated in indirect and direct rapid tooling manufacturing technology with its application prospective foreground. The research on the effect of metal powder on the capability of modeling epoxy colophony has adopted the way in which all kinds of metal powder has been added into the domestic produced epoxy colophony. It has also done the research into RE and RP technology of metal powder filling epoxy colophony in rapid tooling manufacturing theory and practice.The research fruit has some reference value on rapid tooling manufacturing technology research and on rapid engineering technology and rapid prototyping technology. And it has some guidance significance in practical application in metal colophony technics.It has provided new approaches in rapid toolling manufacturing technology and practical production. It has relative high economic efficiency and applicable value.
